GRAIN-DRILL.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application fil d February 5, 1906. Serial No. 299,661.

To all whom it may concern:

Be it known that I, WVILLIAM FETZER, a citizen of the United States,residing at Mid.- dletown, in the county of Butler and State of Ohio,have invented certain new and useful Improvements in Grain-Drills, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to an improvement in grain-drills, and moreparticularly to the mechanism utilized for lifting or depressing drills,furrow-openers, or hoes for such graindrills.

The invention comprehends a foot-board secured to the machine andextending transversely of the drills and means for lifting anddepressing the drills, including a lever movable transversely of themachine and arranged to swing wholly in a plane at one side of thefoot-board and within easy reach of an operator standing thereon, and inthis respect has reference to the subject-matter disclosed in myapplication which resulted in the grant of Patent No. 752,618, datedFebruary 16, 1904, and wherein the same is shown as a modified form.

In the drawings, wherein like letters of reference refer to similarparts in the several views and wherein a preferable embodiment of myinvention is shown, Figure 1 is a vertical longitudinal section throughmy improved grain-drill. Fig. 2 is a horizontal section on line 2 2 ofFig. 1. Fig. 3 is a detail view showing the manner of securing thefootboard hangers to the frame. Fig. 4 is a cross-section on line 3 3 ofFig. 1. Fig. 5 is a detail view in elevation of the operatinglever forcontrolling the height of the drills, and Fig. 6 is a cross-section online 6 6 of Fig. 5.

Referring now more particularly to the drawings, the frame of myimproved drill comprises the side pieces A A and the transverseconnecting members B.

O designates the hopper for the grain, which extends transversely of themachine and has secured to the ends thereof castings 0, provided withdownwardly-extending lugs or arms 0, which-are adapted to be secured bysuitable clamping-bolts to the side pieces A A of the frame.

D designates the axle of the machine,which is supported in suitablebearings (Z, secured to the side pieces A A of the frame by suit ableclamping-bolts.

E designates a foot-board, which when in place occupies a positionadjacent the ground just in rear of and parallel with the hopper C. Thefoot-board E is supported upon brackets 6, each of which consists of abody portion arranged to underlie the footboard, and an overhanging lipe, which is adapted to abut against and overlie the edge of thefoot-board. The brackets e are each secured to the frame of the machineby two sets of hangers e, the lower ends of which are secured in pockets6 formed in the brackets e on opposite sides and adjacent the rear endthereof, and the upper ends of which are secured to the side pieces A Aof the frame by the clampingbolts which clamp the rearmost lugs c of thehopper-casting c thereto and the clampingbolts which secure the bearings12 of the axle to the side pieces.

F designates the furrow-openers, the bearings for which are pivotallysupported in any suitable manner to the frame of the machine and whichmay be of any approved type. The furrow-openers are provided with theusual seed-tubes, which extend from the seedhopper O.

G designates a rock-shaft ournaled between the side pieces A A of theframe. The rock-shaft G has secured thereto a plurality of arms g, whichengage rods f, secured to the bearings of the furrowopeners F so thatthey may be elevated, and also engage springs f, which surround saidrods, so that the furrow-openers may be forced downwardly under ayielding pressure.

H designates a brace which is secured to one of the transverseconnecting members B of the frame and extends rearwardly therefrom, saidbrace being apertured at its free end to afford a bearing for thecentral portion of the rock-shaft G.

I designates a casting which is secured to the rear side of theseed-hopper O and is provided with a downwardly-extending arm 'i, whichis rigidly connected at its lower end in any suitable manner to thebrace H, and with a plurality of arms i, the outer ends of which carry asegmental rack 11 The free ends of the arms t" are slightly offset, sothat the segmental rack 17, carried thereby, will when the casting I issecured to the rear side of the hopper C be positioned a slight distancetherefrom. The downwardly-extending arm i of the casting I is providedwith a longitudinally-disposed groove 01 therein for a purpose to behereinafter set forth.

K designates a lever which is pivotally secured to the central portionof the casting I and which is provided at the lower end thereof with agear-like portion is. The lever K is also provided with a pawl k, whichis adapted to cooperate with the segmental rack 11 to hold the lever inany desired position of ad justment, and with the usual hand-grip forelevating said pawl to disengage the same from the rack.

L designates a bar which is adapted to move longitudinally over theupper surface of the downwardly-extending arm i of the casting I, theupper end of said bar being arranged to underlie the segmental rack iand the lower end of said bar being provided with an inwardly-extendinglip Z, arranged to underlie the downwardly-extending arm i. The bar L isprovided on its under side with a longitudinally-disposed tongue Z,which is adapted to engage the groove t in the downwardly-extending arm& to prevent lateral movement of said bar thereon, and along one edgewith a tooth portion of rack 1 which is adapted to mesh with thegear-like portion is of the lever K. The bar L is provided at its lowerend with an offset foot 1 which has formed therein ahorizontally-disposed slot Z.

M designates an arm which is rigidly secured in any suitable manner tothe rockshaft G and is provided at its free end with alaterally-disposed stud m, which projects into the horizontal slot Z,formed in the foot Z of the bar L.

From the above-described construction it will be apparent that when thelever K is actuated the bar Lwill be raised or lowered, which, owing toits connection with the arm M, will rock the shaft G, and thereby effectthe raising or lowering of the furrow-openers.

From the above-described construction it will be apparent 'that inasmuchas the lever for manipulating the furrow-openers is movable transverselyof the machine and is positioned at one side of the footboard it isalways accessible to the operator standing thereon and at the same timedoes not in any way interfere with his movements.

While I have described the segmental rack and the lever carried therebyas being secured to the seed-hopper, it is obvious that they might besupported in any suitable manner from the frame proper of the machinebetween the foot-board and said hopper. It will also be obvious that anydesired form of furrow-openers may be used and any means may be employedfor connecting the reciprocating rack-bar therewith to effect theraising and lowering thereof.
